Description
Technical Field
[0001] This utility model relates to the field of bogie press-fitting, specifically to a bogie guide column positioning press-fitting device. Background Technology
[0002] The bogie is the running gear of a rail vehicle, much like a person's legs, and is one of the most crucial components of a rail vehicle.
[0003] The various parameters of the bogie directly determine the vehicle's stability and ride comfort.
[0004] In subway maintenance, the inspection of bogies is an essential procedure. The current method involves using fixtures to place the bogies, and then using the fixtures' structures to position, press, or clamp them. Generally, bogies require centering at both ends, downward pressing at both ends, and downward pressing in the middle. These positioning points allow for relatively accurate determination of the bogie's position, thus providing a foundation for subsequent automated and intelligent maintenance and disassembly.
[0005] In actual use, the existing device cannot move synchronously, which makes the bogie prone to deviation and causes positioning errors. At the same time, the device has poor clamping effect, which makes the bogie uneven and tilted upwards. Utility Model Content
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A positioning and pressing device for bogie guide columns includes a placement seat, a protective cover fixedly sleeved on the lower end of the placement seat, ear plates symmetrically fixedly installed on both the front and rear sides of the placement seat, a support column fixedly installed on the lower end of the ear plates, an adjustment mechanism symmetrically installed on both sides of the placement seat, a fixed seat installed at the front end of the adjustment mechanism, a connecting frame fixedly installed on the upper end of the fixed seat, and a pressing mechanism connected to the inner side of the connecting frame.
[0008] A further improvement of this utility model's technical solution lies in the following: the adjustment mechanism includes a connecting plate, a motor is fixedly installed on the inner side of the connecting plate, a gear is driven by the motor output rod, slots are symmetrically opened on the left and right sides of the placement seat, a gear is rotatably installed inside the slots, movable slots are symmetrically opened on the upper sides of the placement seat, guide slots are symmetrically opened on the front and rear sides of the movable slots, a toothed plate is slidably installed inside the movable slots, guide blocks are symmetrically fixedly installed on the front and rear sides of the toothed plate, and sliding grooves are symmetrically opened on the front and rear sides of the upper end of the placement seat, with sliders slidably installed inside the sliding grooves.
[0009] A further improvement of this utility model is that: the first gear meshes with the second gear, and the second gear meshes with the lower end of the toothed plate.
[0010] A further improvement of this utility model is that the guide block matches the guide groove and is slidably connected, and the top of the toothed plate and the slider is fixedly connected to the rear end of the fixed seat.
[0011] A further improvement of this utility model is that: the clamping mechanism includes a hydraulic cylinder, the lower end of the hydraulic cylinder is fixedly installed on the top of the connecting frame, a lifting plate is fixedly installed on the top of the output rod of the hydraulic cylinder, a plurality of equidistant telescopic columns are fixedly installed on the lower end of the lifting plate, a spring is sleeved on the outside of the telescopic column, and a clamping plate is fixedly installed on the lower end of the telescopic column.
[0012] A further improvement of this utility model is that one end of the spring is fixedly connected to the lower surface of the lifting plate, and the other end is fixedly connected to the upper surface of the pressing plate.
[0013] A further improvement of this utility model is that a rubber anti-slip pad is glued to the lower end of the pressing plate.
[0014] A further improvement of this utility model is that the connecting frame is "L" shaped.
[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0016] 1. This utility model provides a positioning and pressing device for bogie guide columns. Through the adjustment mechanism, and with the cooperation of a connecting plate, motor, gear one, slot, gear two, movable slot, guide slot, toothed plate, guide block, slide groove, and slider, the rotating gear two can drive the meshing toothed plate to move, so that the toothed plate pushes the fixed seat to move, so that the two sets of fixed seats gradually move closer or further apart, thereby preventing the bogie from shifting when pressed, thus improving the positioning effect.
[0017] 2. This utility model provides a bogie guide column positioning and pressing device. Through the pressing mechanism, with the cooperation of hydraulic cylinder, lifting plate, telescopic column, spring and pressing plate, the pressing plate can press the two sides of the bogie to prevent the bogie from being uneven or tilting upwards, thereby improving the use effect of the device.

[0024] The present invention will now be described in further detail:
[0025] like Figures 1 to 5 As shown, this utility model provides a positioning and pressing device for bogie guide columns, including a placement seat 1, a protective cover 2 fixedly sleeved on the lower end of the placement seat 1, ear plates 3 symmetrically fixedly installed on both the front and rear sides of the placement seat 1, a support column 4 fixedly installed on the lower end of the ear plates 3, an adjustment mechanism 5 symmetrically installed on both sides of the placement seat 1, a fixed seat 6 installed at the front end of the adjustment mechanism 5, a connecting frame 7 fixedly installed on the upper end of the fixed seat 6, and a pressing mechanism 8 connected to the inner side of the connecting frame 7.
[0026] The connecting frame 7 is L-shaped.
[0027] The protective cover 2 can protect the two sets of motors 52 and prevent them from being damaged. The support column 4 can support the placement seat 1, thereby improving the stability of the support column 4.
[0028] like Figure 3-4As shown, the adjustment mechanism 5 includes a connecting plate 51, a motor 52 is fixedly installed on the inner side of the connecting plate 51, a gear 53 is installed on the output rod of the motor 52, slots 54 are symmetrically opened on the left and right sides of the placement seat 1, a gear 55 is rotatably installed inside the slots 54, movable slots 56 are symmetrically opened on the upper side of the placement seat 1, guide slots 57 are symmetrically opened on the front and rear sides of the movable slots 56, toothed plates 58 are slidably installed inside the movable slots 56, guide blocks 59 are symmetrically fixedly installed on the front and rear sides of the toothed plates 58, and sliding grooves 510 are symmetrically opened on the front and rear sides of the upper end of the placement seat 1, and sliders 511 are slidably installed inside the sliding grooves 510.
[0029] Gear 1 53 meshes with gear 2 55, and gear 2 55 meshes with the lower end of gear plate 58.
[0030] The guide block 59 matches the guide groove 57 and is slidably connected. The top ends of the toothed plate 58 and the slider 511 are fixedly connected to the rear end of the fixed seat 6.
[0031] When the toothed plate 58 moves, it drives the guide block 59 to slide in the guide groove 57, thereby improving the smoothness of the movement of the toothed plate 58. When the fixed seat 6 moves, it drives the slider 511 to slide in the slide groove 510, thereby improving the stability of the movement of the fixed seat 6.
[0032] like Figure 5 As shown, the clamping mechanism 8 includes a hydraulic cylinder 81. The lower end of the hydraulic cylinder 81 is fixedly installed on the top of the connecting frame 7. A lifting plate 82 is fixedly installed on the top of the output rod of the hydraulic cylinder 81. Multiple sets of equidistant telescopic columns 83 are fixedly installed on the lower end of the lifting plate 82. A spring 84 is sleeved on the outside of the telescopic column 83. A clamping plate 85 is fixedly installed on the lower end of the telescopic column 83.
[0033] One end of the spring 84 is fixedly connected to the lower end surface of the lifting plate 82, and the other end is fixedly connected to the upper end surface of the pressing plate 85.
[0034] The lower end of the clamping plate 85 is glued with a rubber anti-slip pad.
[0035] The rubber anti-slip pads will first contact the sides of the bogie, which avoids increasing the friction of the pressure plate 85, thus improving the pressing effect and preventing clamping marks on the bogie.
[0036] The working principle of the bogie guide column positioning and pressing device will be explained in detail below.
[0037] like Figures 1 to 5As shown, the bogie guide column positioning and pressing device, when in use, can first be adjusted according to the bogie size. The motor 52 can be started, and the output rod of the motor 52 drives gear 1 53 to rotate, causing gear 1 53 to drive the meshing gear 2 55 to rotate within the slot 54. Gear 2 55 then drives the meshing toothed plate 58 to move within the movable slot 56, causing the toothed plate 58 to move synchronously with the fixed seat 6. This allows adjustment of the distance between the two sets of fixed seats 6, facilitating the positioning and pressing of the bogie. After adjustment, the bogie can be placed on the placement seat 1, simultaneously positioning the two sides of the bogie on the placement seats... On the fixed seat 6, the hydraulic cylinder 81 can then be activated. The output rod of the hydraulic cylinder 81 pushes the lifting plate 82 downward, so that the lifting plate 82 drives the pressing plate 85 to move synchronously through the telescopic column 83. This allows the pressing plate 85 to contact the two sides of the bogie, thereby positioning and pressing the bogie. At the same time, the hydraulic cylinder 81 can continue to push one end of the lifting plate 82 downward, thereby squeezing the telescopic column 83 and the spring 84. Under the action of the deformed spring 84, the pressing plate 85 can be squeezed downward, thereby improving the pressing effect of the pressing plate 85 on the bogie and preventing it from shifting.
[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
